In this activity, I
used IRIS dataset and after fitting KNN algorithm on the data and the
transformed ones with PCA method (Dimensionality Reduction), I compared the
Train and Test Accuracy Changes. In 3 features we didn’t have noticeable
improvement, however 1 feature deteriorates the accuracy, while considering 2 features
boosts it.
